the best compounds with dual cholinesterase and amyloid aggregation inhibition. The picolylamine‐substituted compound 12c (6‐chloro‐N‐(pyridin‐2‐ylmethyl)‐1,2,3,4‐tetrahydroacridin‐9‐amine) was the most potent AChE inhibitor (IC50 = 90 nm). These investigations demonstrate the utility of 3,4‐dimethoxyphenyl substituent as a novel pharmacophore possessing dual cholinesterase inhibition and anti‐Aβ‐aggregation
设计,合成并评估了取代的四氢ac啶九胺衍生物库,将其作为双重胆碱酯酶和淀粉样蛋白聚集抑制剂。化合物8E(N- (3,4-二甲氧基苄基)-1,2,3,4- -1,2,3,4-四氢吖-9-胺)被确定为丁酰胆碱酯酶的强效抑制剂(BuChE的IC 50 = 20n中米;乙酰胆碱酯酶IC 50 = 2.2 μ米),并能抑制淀粉样蛋白聚集(25 40%抑制 μ米)。化合物9E(6-氯- N-(3,4-二甲氧基苄基)-1,2,3,4- -1,2,3,4-四氢吖-9-胺,乙酰胆碱酯酶IC 50 = 0.8 μ米; BuChE的IC50 = 1.4 μ米; Aβ聚集抑制= 75.7%抑制,在25 μ米)和11B(6-氯- N-(3,4-二甲氧基苯乙基)-1,2,3,4- -1,2,3,4-四氢吖-9-胺,乙酰胆碱酯酶IC 50 = 0.6 μ米; BuChE的IC 50 = 1.9 μ米;
